05c8d0bce6 avfilter/avf_concat: check for possible integer overflow 
Also check that segment delta pts is always bigger than input pts.

There is nothing much currently that can be done to recover from
this situation so just return AVERROR_INVALIDDATA error code.

2f76476549 lavfi: regroup formats lists in a single structure. 
It will allow to refernce it as a whole without clunky macros.

Most of the changes have been automatically made with sed:

3ad5d4df9c lavfi/concat: allow to support inputs with different frame rates 
Right now, the concat filter does not set the frame_rate value on any of
the out links. As a result, the default ffmpeg behaviour kicks in - to
copy the framerate from the first input to the outputs.

If a later input is higher framerate, this results in dropped frames; if
a later input is lower framerate it might cause judder.

This patch checks if all of the video inputs have the same framerate, and
if not it sets the out link to use '1/0' as the frame rate, the value
meaning "unknown/vfr".

A test is added to verify the VFR behaviour. The existing test for CFR
behaviour passes unchanged.

d723994449 avfilter/avf_concat: add next command 
This patch makes it possible to dinamically close the current segment
and step to the next one by introducing command handling capabilities
into the filter. This new feature is very usefull when working with
real-time sources or live streams as source. Combinig usage with zmqsend
tool you can interactively end the current segment and step to next one.

6aaac24d72 avfilter/all: propagate errors of functions from avfilter/formats 
Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM).
This propagates the return values.

All of these were found by using av_warn_unused_result, demonstrating its utility.

Tested with FATE. I am least sure of the changes to avfilter/filtergraph,
since I don't know what/how reduce_format is intended to behave and how it should
react to errors.

Fixes: CID 1325680, 1325679, 1325678.
